Problems solved by technology

The above-mentioned existing technical solution has the following defects: although the cement mixing pile can weaken the degree of uneven settlement of the above-mentioned composite foundation, after the above-mentioned road surface is put into use, the vehicle basically drives in the central area of ​​the road, so that the settlement of the central area of ​​the road needs to be It is obviously stronger than the areas on both sides of the road. With the increase of the time the road is put into use, the road surface will have different degrees of bulges or depressions. In severe cases, longitudinal cracks will appear on the road surface. Road Construction Technology with Uneven Settlement in the Areas on Both Sides of the Road and in the Center Area

Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] A road construction process, defining the length direction of the road made by the road construction process as the longitudinal direction, and defining the width direction of the road made by the road construction process as the transverse direction, comprising the following steps:

[0047] S1, such as figure 1 As shown, excavating the first foundation pit 1: using an excavator to excavate the first foundation pit 1, the cross section of the first foundation pit 1 is in the shape of an inverted isosceles trapezoid.

[0048] S2. Setting the strengthening structure of the first foundation pit 1, which specifically includes the following steps:

[0049] S21. Clean up the bottom surface of the first foundation pit 1, and carry out the pile position stakeout of the first cement mixing pile 12 on the bottom surface of the first foundation pit 1, and the pi...

Abstract

The invention discloses a road construction process which solves the problem that differential settlement occurs in the center area and the two sides of a road. According to the technical scheme, theroad construction process is characterized by comprising the following steps: S1, excavating a first foundation pit; S2, arranging a first foundation pit strengthening structure; S21, conducting a pile position lofting of a first cement mixing pile; S22, arranging a first cement mixing pile according to the pile position lofting point; S23, before the first cement mixing pile is solidified, excavating a plurality of transverse grooves longitudinally at intervals of at least one set of first cement mixing piles in a way that at least one set of first cement mixing piles are located in the transverse grooves; S24, laying a first reinforcing part in the transverse groove, wherein the first reinforcing part is provided with a first reinforcing part; S25, filling and tamping the transverse grooves with undisturbed soil and tamped; S3, laying a first light soil layer; S4, laying a first stable layer; and S5, laying a first surface layer. The central area and the two side areas of the road manufactured according to the road construction process are not prone to differential settlement.

Description

technical field [0001] The invention relates to a road construction technology. Background technique [0002] With the development of cities, the coverage of urban roads to cities is gradually increasing, and road construction is an indispensable part of urban construction. Authorized announcement number is that the Chinese utility model patent of CN203684254U discloses a kind of cement-soil mixing pile composite foundation, comprises road base, cushion course and cement mixing pile. The above-mentioned existing technical solution has the following defects: although the cement mixing pile can weaken the degree of uneven settlement of the above-mentioned composite foundation, after the above-mentioned road surface is put into use, the vehicle basically drives in the central area of ​​the road, so that the settlement of the central area of ​​the road needs to be It is obviously stronger than the areas on both sides of the road. As the road is put into use, the road surface wi...
